Chameleon
Lower (1.5)Sign language to avatar tool using Unreal Engine
Chameleon is a specialized tool developed by Wycliffe Bible Translators that transforms multi-camera sign language recordings into avatar-based outputs using Unreal Engine. It represents a unique technical innovation aimed at supporting accessibility and scale in sign language Bible translation.
Detailed Sustainability Scores
Chameleon is fully funded through WBT-raised funds, which has enabled its development and use. While this model has been sustainable thus far, its long-term viability is uncertain. Nevertheless, Chameleon offers a more effective and higher-quality alternative to traditional methods and has received positive feedback from multiple translation teams.
The tool is deeply integrated with Unreal Engine, benefiting from its extensibility and standard outputs. However, its reliance on Unreal makes it less adaptable to technologies outside that ecosystem. This tight coupling restricts broader technical integration and limits extensibility across other translation platforms.
Chameleon actively engages users through field workshops and in-office demos. Designed for moderately technical users, the tool aligns well with its intended use cases. The team has implemented multiple improvements based on user input, reflecting a strong feedback loop and responsiveness to evolving needs.
While Chameleon can operate offline, it requires high-end hardware and a complex setup with approved multi-camera rigs. These infrastructure demands present a barrier to adoption, particularly in low-resource environments. Localization status is unclear. Despite this, Chameleon addresses a critical, under-served need in the translation of sign languages.
Chameleon is not open-source, and its technical complexity makes handoff or external maintenance challenging. There's no clear documentation available for independent developers, and currently WBT is the only organization managing the tool. These factors pose a risk to long-term continuity if internal priorities shift.
While Chameleon benefits from Unreal Engine's standard framework, the tool itself is not designed for reuse and is not open-source. There is no developer-facing support or public documentation to enable integration, limiting its contribution to broader ecosystem collaboration.
WBT's participation in ETEN offers indirect alignment with collective goals like AAGs and EVC. However, strategic collaboration with broader movement partners is limited, and Chameleon currently functions more as a focused, standalone solution rather than a platform contributing toward shared infrastructure or goals.
Key Strengths

- Addresses critical under-served translation need
Key Recommendations
- Publish documentation to support future handoff or outside contributions
- Explore pathways for reuse or integration with other sign language tools
- Reduce hardware complexity to expand accessibility
- Clarify role within broader strategic initiatives to align more deeply with the translation movement
- Consider open-source approach to improve long-term sustainability
Key Sustainability Variables
1. Financial Viability, Cost-Effectiveness & Funding Sustainability
How financially viable (including all funding sources) is this solution over its lifecycle, and what regularly measurable Return-on-Investment towards major milestones (AAGs and EVC) does it offer in terms of demonstrated strategic value, efficiency and impact when compared to other relevant options?
2. Technical Adaptability, Interoperability & Extensibility
How well does the solution (regardless of size) adapt to emerging technologies (e.g. AI), integrate with existing systems, and iteratively update or extend functionality in order to reduce the frequency of complete overhauls?
3. User-Centric Adaptability & Responsiveness
How effectively does the solution continuously incorporate user feedback and remain responsive to changing needs and workflows, ensuring intuitive design and long-term cultural relevance across diverse global contexts?
4. Global Accessibility & Local Adoption
Can the solution be effectively used across all regions, and what barriers—technical (e.g. complex scripts, oral, sign), cultural (e.g. localization, customization, training), or infrastructural (e.g. scalable, offline, mobile)—might limit its accessibility (open-access) or local adoption (e.g. security risks), and does it demonstrate alignment with unmet user needs (market fit)?
5. Open Collaboration & Organizational Continuity
What is the likelihood and impact if the current development team or organization loses interest or shifts focus, and who (e.g. cross-organizational trust, capability, and knowledge-sharing) as well as what mechanisms (e.g. open-source, documentation, technical maturity, operational capacity) are in place to pick up the baton and maintain continuity?
6. Technology Standards, Reusability & Developer Support
To what extent are the parts of the solution reusable across similar solutions, and how actively does the organization pursue transparency and collaboration to enable reuse, reduce duplication across organizations, promote best practices, and advance common open standards (e.g. tech stack, frameworks, platforms) to collectively maximize the amount of work-not-done across solutions and devices?
7. Identifying with the Collective Impact Alliance
How closely does the team or organization align their identity, priorities, and efforts with the shared values and collective strategic milestones (e.g. AAGs and EVC) of the broader Bible translation movement, rather than becoming overly identified with specific solutions which may not directly advance these collective objectives?
